  ABSTRACT: In recent years many biomedical ontologies have been developed and many of these ontologies contain overlapping information. To be able to use multiple ontologies they have to be aligned. In this paper we propose strategies for aligning ontologies based on life science literature. We propose a basic algorithm as well as extensions that take the structure of the ontologies into account. We evaluate the strategies and compare them with strategies implemented in the alignment system SAMBO. We also evaluate the combination of the proposed strategies and the SAMBO strategies.

  ABSTRACT: More and more people are living to old age, and it is usually a desire among elderly to sustain mobility. Unfortunately, the crash rate of older adults is much larger than for other drivers. Older drivers are also more likely to get serious injuries that lead to disability or death. Therefore, technological contributions for improving traffic safety and preserve mobility of older people are important. One new promising approach is to use traffic safety systems based on vehicular communication, where vehicles exchange warning messages. This paper evaluates the feasibility of using such vehicular communication for supporting older drivers in road intersections, which is the most common accident setting for older drivers.

• Article: Dependability Requirements to Aid the Design

  ABSTRACT: Frail older people can normally not be given round-the-clock care-giving assistance. During the time there is no other person around they must be independent. Electronic assistive technology (EAT) can increase an older person's independence in everyday life, but to do so it must be dependable.
